+++ Description
- The Yacheng field has estimated reserves of more than 3-trillion cubic feet of gas, making it the largest offshore natural gas producing field in China
- Yacheng 13-4 Gas Field is a satellite
- The gas is mostly transported to Hong Kong through a 480-mile pipeline, the second longest subsea pipeline in the world.
- A second pipeline supplys natural gas to local industries on Hainan Island some 60 miles away.

+++ Geology
- The primary reservoir is the Middle/Late Oligocene Lingshui-3 Member sandstones, which were developed during a major marine transgression in response to the continued opening up of the South China Sea. The thermal subsidence during late syn-rift stage created substantial accommodation space that contributed to the development of overwhelmingly thick succession (over 150 m) of reservoir sandstones with excellent reservoir quality.
